SHUTTLE-MOTION FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 339,239, dated April6,1886.

Application filed October 22,1884. Serial Nod-16,231. (No model.)

To all whom, t may concern:

Be it known that I, Tnnononn A. WEBER, of New York, in the county of NewYork and the State of New York, have invented a certain new and usefulImprovement in Shuttle- Motions for Looms, of which the following is aspecification.

I will describe a loom embodying my improvement, and then point out theimprovement in claims.

In the accompanying drawings, Figure l is a plan view of parts of a loomembodying my improvement, and Fig. 2 is a front elevation of the same. A

I have deemed it necessary to illustrate only such parts of a loom asembody my improvement. Other necessary parts of the loom may be of anyapproved type.

A designates two side pieces, comprised in the frame of the loom.

B designates a shaft, which transmits -motion to the parts which embodymy improvenient, and which I am about to describe. This shaft isjournaled in the side pieces, A, and driven in any suitable manner. Nearthe side pieces, A, the shaft B has amxed to it bevel gear-wheels c c.rlhese bevel gear-wheels mesh with other bevel gear-wheels, b b, whichare rigidly secured to vertical shafts O O. As here shown, these shaftsC C are supported in bearings in inwardly-projecting brackets c c',attached to the side pieces, fA. At the upper ends the shafts O C havedisks c2 c3 affixed to them. These disks have upon their under sideshubs c4 c5, which rest upon the inwardlyprojecting brackets c c of theside pieces, A, and support the shafts vertically.

D D designate levers, fulcrumed at the rear ends to pins or studs p p,supported by pro- 40 jections from the side pieces, A. These levers areswung to and fro to impart motion to the shuttles.

Motion is transmitted to the lever D by means of a crank-pin, E,projecting from the disk cI of the shaft C, a link-connection beingemployed between the wrist-pin and the lever. As here shown, thecrank-pin has loosely fitted upon it a bar, d, and links d d2 arepivotally connected to the latter and to the lever D. By these means Iam enabled to produce dwells77 of the lever at the ends of itsmovements, because the crank-pin E at certain portions of its strokewill not impart any appreciable swing to the levers D D on their fulcra.The front end of the lever D is pivotally connected to one end of alink, d, which at the other end is pivotally connected to a carriage, F.The carriage F is reciprocated along ways or guides Gr by the to-and-fromovements of the lever D. As shown, the side edges ofthe carriage workin grooves in the ways or guides. The ways or guides are secured to theside pieces, A.

H H are levers, which are fulcrumed between the ends upon studs f f,projecting from the carriage F near its forward end, or, in other words,near the end which is the nearer to the middle of the loom. The forwardends of the levers H H are adapted to grip the shuttles which areemployed in the loom. To adapt the loom for using two shuttles, theforward ends of the levers are bifurcated, or, in other words, severallyhave two portions, f" f3, one above the other. Nearthe rear ends 'thelevers H H are provided with longitudinal slots s. Passing looselythrough the slots s are screws or pins f* f, projecting from the endportions of a bar, f, which is affixed to the upper end of a verticalrock-shaft, f7.

W'hen the shaft j" is rocked into a position at about right angles tothe length of the levers H H', these levers will be forced as far apartas possible at their rear ends, and consequently as close as possibletogether at their forward ends. The forward ends will then grip shuttlesinserted between them. At the lower end the shaft f i has affixed to itan arm, f8. By shifting this arm f8 the shaftf7 will be rocked, so as tooperate the levers I-I H.

The lever D is connected to a crank-pin, E', projecting from the disk c3of the shaft C, and derives its swinging motion from such crankpin. Itis connected to the said crank-pin by means of a bar, d, loosely mountedon the crank-pin, and having a pivotal connection with links d d?, whichare also pivotally connected with the lever D. This bar` d and the linksd di are used in the same way and for the same purpose as the bar andlinks similarly lettered, which I have heretofore described.

The front end of the lever D is pivotally connected to one end of alink, di, which, at the other end, is pivotally connected to a car- IOOriage, F. Then the lever D is oscillated or swung to and fro, thiscarriage is reciprocated correspondingly along ways or guides G', whichmay be'similar to the ways or guides for the carriage F.

H2 H3 designate levers arranged u pon the carriage F'. They are like thelevers H H',which are arranged upon the carriage F. They are fulcrumedupon studs fgfw, projecting from the carriage F', near the forward endof such carriage, or, in other words, near the end which is the nearerto the' middle of theloom. The Yforward ends of the levers H H3 areadapted to grip the shuttles. In order that two shuttles may be used,the forward ends of these levers are bifurcated, each having twoportions, f f, one above the other. Near the rear ends the levers H2 H3have longitudinal slots s, into which extend screws or pins fif,projecting from abar, f. This barf15 is affixed to the upper end of avertical rockshaft, fm, which is journaled in the carriage F', and hasaffixed to itslower end an arm, f. By shifting Vthe arm f therock-shaftfl will be rocked, and the bar f will oscillate the levers H2H in such manner that the forward ends of the latter will alternatelyapproach and recede from each other to grip and release the shuttles.

The movementsof the carriages F F' are so timed that they will approacheach other and recede from each other together. The motions of the pairof levers H H', mounted on the carriage F, and of the pair of levers H2H3, mounted on the carriage F', are so timed that when the carriagesmove into proximity the forward ends of one pair of said levers willmove apart and the forward ends of the other pair of said levers willmove toward each other, wherefore when the carriages come close togetherthe shuttles will be transferred from one carriage to the other.

In order that the shuttles may always be transferred from one carriageto the other every time the carriages move into proximity with eachother, it is necessary that the forward ends of the pair ofshuttle-gripping levers of each carriage shall move together on oneoccasion when the carriages move into proximity, and move apart on thenext occasion when the carriages move into proximity, and so onalternately.

I will now describe the means whereby the shafts f 7 f 1G are rocked forthe purpose of operating the Shuttle-gripping levers H H' and HZ H3.

I I designate levers which are fulcrumed between theY ends to bars G2G3, extending between the ways or guides G G'. These levers work in thesame horizontal plane as the arms f B f, which are affixed to the shaftsf7 fm. Then the carriages move into proximity with each other, the armsfS f1T come in contact with the levers I I', and are shifted so as torock the shafts f7 f1, because the levers I I will at those times beadjusted at such angles that the arms f8 f 17, by abutting against them,will be shifted properly.

The levers I I' are connected together by a link, I2. The lever I hasupon its under side lugs z', in which a rod, I3, ts in such way,

that while any swinging movement which may be imparted to it will betransmitted to the lever I, yet it will be free to slide lengthwiseofthe lever I. This rod I3 is pivotally connected to a lever, I4, whichis pivotally connected by a link, I, with a crank pin, I, projectingfrom a gear wheel, J. The gearwheel J is mounted on a shaft which issupported by one of the side pieces, A, of the frame. It derives motionfrom a gear-wheel, J', having one-half the number of teeth which, ithas, and affixed to the shaft C. 'Each time the shaft C makesfadcomplete rotation it moves the carriage F as far toward the carriageF as it can go. The shaft C at the same time moves the carriage F' asfar toward the carriage F as it can go. During each rotation of theshaft C the gear-wheel J makes only a half-rotation. Owing to this thewheel J will shift the levers I I into a different position during eachone-half rotation it makes. It is because the levers I I occupy adifferent position each time the carriages F F' move into proximity thatthe forward ends of each of the pairs of shuttle-gripping levers HH'andH2 H3 will move toward each other one time when the carriages move intoproximity, and move away from each other the next time the carriagesmove into proximity, and so on.

The shuttles are to have grooves in thesides, into which the portions f2f3 of the levers H H' and f u f 12 of the levers H2 H3 will t.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of carriages provided with pairs of shuttle gripperlevers, guides for said carriages, means, substantially such asdescribed, for reciprocating said carriages, oscillating bars connectedwith the said shuttlc-gripper levers, arms connected to the saidoscillating bars, so as to move in unison therewith,V movable levers forshifting the said arms,and mechanism,substantially such as described,having a connection with one of said levers,which will enable it to becaused to act nearer to or farther from the fulcrum of said lever,substantially as specified.
